BUG: Series.plot(kind="pie") does not respect ylabel argument

[WillAyd]

Pandas version checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pandas.

• I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

ser = pd.Series([1, 2, 4], index=["a", "b", "c"], name="my_series")
ser.plot(kind="pie", ylabel=None)

### Issue Description

The plot will always show the label "my_series", regardless of if you pass ylabel=None or not.

The only way to fix this is to do:

```python
ax = ser.plot(kind="pie")
ax2.set_ylabel(None)

Expected Behavior

ylabel argument should be respected

Hi @WillAyd since the default for ylabel is None, the pie will never show label if that is not defined. Will never get the name of the Series as the behavior now. Is that what is expected?

[WillAyd]

Yea I think that is correct. I don't think any of the other chart types do that, so would be good to make them all consistent
